Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a positioning device for a mounting board of an electronic component, in which lateral movement of a clamp member and a pushing-up member of the board is performed in response to a change in board size. And, the substrate can be easily pushed up by the pushing member.

(Prior Art) An apparatus for positioning a mounting board of an electronic component in a thick film printing apparatus, an electronic component mounting apparatus, a visual inspection apparatus, etc., includes a means for positioning the board by sandwiching the board from both sides with a pair of clamp members. It comprises means for pushing up the substrate from below in order to eliminate the inclination of the substrate due to the unevenness of the surface of the conveyer belt conveyor and keep the substrate horizontal.
FIG. 3 shows such a conventional positioning device, in which 100 is a substrate, 101 and 102 are clamp members, 103 is a belt conveyor, and 104 and 105 are lifting members.

By the way, when the width of the board is changed due to the change of the board, the clamp members 101, 102 and the push-up members 104, 105 must be moved laterally to adjust the position. Conventionally, as means for moving the push-up members 104, 105 in the lateral direction, a base plate 106 is provided below the push-up members 104, 105, and pins 10 are provided in pin holes 107 formed at a pitch on the base plate 106.
It was done by inserting 8. Reference numeral 109 is a push-up device for the receiving plate 106 made up of a cylinder.

(Problems to be solved by the invention) However, in the above-mentioned conventional means, in order to perform width adjustment, a pin is used.
Remove the pin 108 from the pin hole 107, move the push-up members 104, 105 laterally to adjust the width, and then insert the pin 108 into the pin hole 1.
Since it had to be inserted into 07 and the clamp members 101 and 102 were moved in the lateral direction to adjust their positions, there was a problem that a great deal of labor and time was required.

Therefore, the present invention responds to changes in the width of the board,
An object of the present invention is to provide means for easily adjusting the positions of a clamp member and a push-up member.

(Means for Solving the Problems) To this end, the present invention provides a pair of clamp members for positioning a substrate conveyed by a conveyor from both sides, and at least one of the pair of clamp members. A lateral movement device for moving in the direction, and a push-up member inside the clamp member that moves laterally integrally with the clamp member and pushes up the substrate from below at its upper end, and the push-up member. The substrate positioning device is constituted by a horizontal plate whose member is slidably grounded in the lateral direction, and an elevating device for elevating the lifting member via the plate.

(Operation) In the above configuration, when the clamp member or the pushing-up member is moved in the lateral direction in order to deal with the change in the width of the substrate, the lateral moving device is driven to integrally move the two in the lateral direction. Move to. Further, when pushing up the substrate carried in between the clamp members to make it horizontal, the pushing device is driven.

(Example) Next, the Example of this invention is described, referring drawings.

FIG. 1 is a perspective view of a board positioning device, and FIG. 2 is a side view, in which 1 is a mounting board for electronic components, and 2 and 3 are the boards 1.
Is a pair of clamp members for sandwiching the substrate 1 from both sides, and 4 and 5 are conveyors made of belts that carry the substrate 1 into and out of the positioning device. 6,
Reference numeral 7 is a member for pushing up the substrate 1, which conveys the substrate 1 to the conveyors 4 and 5.
Then, the substrate 1 is held horizontally by pushing it up slightly. Reference numeral 10 denotes a lateral movement device that laterally moves one clamp member 2, and includes a feed screw 11, a nut 12 that is attached to a lower portion of the clamp member 2, and is screwed to the feed screw 11, and a bearing 13. , An operating unit 14 for manually rotating the feed screw 11. The feed screw 11 may be driven by a power means such as a motor instead of being manually operated.

16,17 is a mounting body attached to the lower part of the lifting members 6,7, 1
8 and 19 are shafts provided below the mounting members 16 and 17, 2
Reference numerals 1 and 22 are rollers rotatably attached to the lower ends of the shafts 18 and 19, 23 and 24 are receiving portions of the shafts 18 and 19, and 25 and 26 are biasing springs. A push-up device 27 for push-up members 6 and 7 is composed of a horizontal plate 28 on which the rollers 21 and 22 are slidably grounded, and a cylinder 29 that pushes up the plate 28 from below. 31 and 32 are XY tables, which move the substrate 1 in the XY directions. As described above, one clamp member 2 slides laterally, while the other clamp member 3 is fixed to the X table 31.

The present apparatus has the above-mentioned configuration, and its operation will be described below.

The substrate 1 conveyed between the clamp members 2 and 3 by the conveyors 4 and 5 is stopped between the clamp members 2 and 3, and in this state, the elevating device 27 is driven and the plate 28 is raised. Then, the push-up members 6 and 7, which are grounded to the plate 28 via the rollers 21 and 22, also rise, and the substrate 1 is pushed up from below by the upper end portion thereof to hold the substrate 1 in a horizontal state. In that state, for example, printing of a print pattern on the upper surface of the substrate 1, visual inspection thereof, mounting of electronic components, visual inspection of mounted electronic components, etc. are performed.
Is lowered and the substrate 1 is placed on the conveyors 4 and 5, and is conveyed to the next step by the conveyors 4 and 5.

Now, when the width of the board changes due to the change of the board,
The positions of the clamp members 2 and 3 and the push-up members 6 and 7 are adjusted.
This position adjustment is performed by manually rotating the operation unit 14. That is, when the operation unit 14 is rotated,
The feed screw 11 rotates, the nut 12 screwed to the feed screw 11 slides laterally, and the one clamp member 2 and the push-up member 6 are
It moves laterally together with the nut 12 to adjust the width between the clamp member 2 and the clamp member 3. At that time, Laura
21 rolls on plate 28. Next, as in the case described above, the lifting device 27 is driven and the plate 28 pushes up the lifting member 6,
7 rises and pushes the substrate 1 from below at its upper end,
The posture of the substrate 1 is kept horizontal. As described above, according to the present device, the positions of the clamp member 2 and the push-up member 6 can be easily adjusted only by rotating the operation unit 14.

The present invention is not limited to the above embodiment, and various design changes are possible. For example, in the above embodiment, only one clamp member 2 is moved laterally, but the other clamp member 3 is used. Similarly, it may be moved laterally.

(Effect of the Invention) As described above, according to the present invention, the positions of the clamp member and the push-up member can be easily adjusted in accordance with the change in the width of the substrate, and the lifting device is driven to interpose the plate. By pushing up the pushing-up member and pushing up the substrate at its upper end, the posture of the substrate can be held in a horizontal state.
